The first job given to Ransburg was the spray painting of a cookie jar. During the course of his job, he began examining and testing various methods to better attract the mists from paint sprayers. Ransburg finally succeeded in developing a system of electrostatic painting called the "No. 1 Process" using a developed piece of equipment that could charge the particles of paint and attract it to the metal. And by the Second World War, the process had gained demand for the painting of bazookas and ammunition boxes.

In 1948, Ransburg introduced an improvised method (cleverly named) the "No. 2 Process". And in 1958, the No. 2 Process hand gun was in common use across many industries – and is still the equipment of choice today.
